30 LANDSCAPE GARDEN SERIES 



When the house is only a short distance from the street, gutters for 

 the car to run in are permissable. They should be 4 feet 8 inches on 

 centers and should be slightly concave so that the driver will have no 

 trouble in keeping the wheels in the tracks. 



Where the property has considerable rise or fall in its grades it is 

 advisable to follow the contour of the ground. This assures an easier 

 grade and makes deep cuts and fills less apt to be required. A grade 

 of 7 per cent or a rise of 7 feet in every 1 feet, is considered the limit 

 of an easy grade, while a 10 per cent grade is considered as steep as 

 a drive should be constructed under normal conditions. The 

 wiclth of walks depends upon their use and location. For main en- 

 trance walks, a width of no less than 4 feet is highly practicable. Serv- 

 ice walks which do not function as part of the design and which are 

 merely hard surfaced paths convenient to walk upon, and direct, can 

 properly be made from 1 J/2 feet up as is determined by the appearance 

 and the demands made upon them.
